Luna Lovegood

captured and escaped

It was believed that Luna was held captive atAzkaban, though she was actually imprisoned in the basement of Malfoy Manor, along with the famed wandmaker Garrick Ollivander, to whom she proved a great comfort. Her father was so desperate to get her back that he tried to turn Harry, Hermione, and Ron over to the Ministry in exchange for her freedom; the trio escaped, but Hermione ensured that the Death Eaters Xenophiliuscalled glimpsed Harry as they left, so that neither he nor Luna would be punished. TheLovegoods' home was largely destroyed with an erumpent horn, which Xenophilius had believed to be a Crumple-Horned Snorkack's, blew up inside. After the failed ambush Xeno was taken to Azkaban prison for the remainder of the war.
The prisoners in Malfoy Manor were soon joined by Harry, Ron, Dean Thomas, andGriphook the goblin, while Hermione wastortured for information upstairs by Bellatrix Lestrange. After Luna helped cut the ropes off their new cell-mates, Dobby the house-elfcame to free them. He took Luna, Dean and Ollivander to Shell Cottage, the home of Billand Fleur Weasley, and then returned to assist Harry, Hermione, Ron and Griphook in escaping the Manor. He died in rescuing them. Up until the Battle of Hogwarts, Luna stayed at the cottage for the remainder of the war, and when Dobby was buried, she closed the house-elf's eyes and provided the eulogy, thanking him for rescuing her. During her stay, she practised using a new wand that Ollivander had made for her. She also seemed to have started a friendship with Dean. It is unknown what Luna did after Harry, Ron and Hermione left Shell Cottage in order to break into Gringotts Wizarding Bank, but she returned to Hogwarts in May when Neville signalled her as to the trio's return. All of Dumbledore's Army was reassembled and prepared to fight.
